Static Optimization

[Christine Dailey]

I read through the Static Optimization tutorial. I'm wondering about the activation-to-force conditions. How will I know which condition to pick? Ideal or constrained by force-length-velocity properties?
Thank you

You can put the following in the .xml file of the SO tool:

Code: Select all

				<!--If true muscle force-length curve is observed while running
					   optimization.-->
        <use_muscle_physiology> true </use_muscle_physiology>
        

You should prefer use_muscle_physiology = true, since the capacity of a muscle to produce force depends on its length and lengthening speed. Otherwise you will assume that fm = fmax * a.

Thank you for your response. Just so I am clear. I will NOT being using ideal. I will be using "constrained by force-length-velocity properties." I wont to double check you are using the word "true" to represent what the muscle are actually doing
